如何在android中的水平Linearlayout中显示两个椭圆形末端的Textview? [英] How to show two Textview with ellipsize end in horizontal Linearlayout in android?

问题描述

我面临的一个问题是，我在一个水平Linearlayout中有两个Textview，在椭圆形末端有一个Textview，当我输入更多文本内容时，它在Textview结尾中显示"..."，但是那时我无法显示第二个TextView.

I am facing one problem which is, I have two Textview in one horizontal Linearlayout and one Textview with ellipsize end and When I have type text more content then it display "..." in Textview ending, But at that time I can not show the second TextView.

但我都想同时使用Textview.如果第一个Textview"具有更多内容，则显示椭圆形"结尾，并显示第二个"Textview".

But I want to both Textview. If First Textview is with more content then it display ellipsize end and also display second Textview.

推荐答案

给第一个孩子Text View而不是第二个孩子.您无需为此使用任何固定宽度.

Give a Weight to your First Child Text View not Second. You not need to use any Fixed width with this.

只需将android:layout_weight="1"分配给第一个孩子Text View.

Just give android:layout_weight="1" to First child Text View only.

请参阅.

    android:layout_height="wrap_content"

我也使其适用于少量内容.我已经删除了嵌套Linear Layouts，这对性能不利.我已对您的Layout进行了更改，请替换为您的XML.

I have made it work for small content also. I have removed Nested Linear Layouts which is bad for performance. I have applied changes to your Layout please replace this with your XML.
